Introduction

Background and significance of nutrition labelling

“Nutrition labelling refers to providing information about the nutritional content of food products on their packaging or labels”.¹ It aims to educate consumers about the composition of the food they consume and assist them in making informed choices regarding their diet and health.² With the rise of chronic diseases such as obesity,³ diabetes,⁴ and heart disease,⁵ there is a growing awareness of the importance of nutrition in maintaining good health. Consumers seek ways to adopt healthier eating habits and make more informed food choices.⁶ Many consumers lack a comprehensive understanding of nutrition and find it challenging to interpret the complex information on food labels.⁷ Traditional nutrition labels often contain technical terms and numerical data that may be confusing or overwhelming for individuals without a background in nutrition.⁸ Nutrition labelling serves to promote transparency in the food industry. It allows consumers to understand the ingredients, nutritional composition, and potential allergens in the food they purchase, fostering trust and accountability between consumers and manufacturers.⁹ Each person has unique dietary requirements, health conditions, and personal preferences. Nutrition labelling has the potential to provide personalized information, enabling individuals to make choices that align with their specific needs, such as managing allergies dietary restrictions, or achieving specific health goals.¹⁰ The inclusion of nutrition labelling on food products has the potential to influence food manufacturers and the broader food industry. Clear and accurate labelling encourages companies to develop and promote healthier food options, reformulate products, and reduce the presence of undesirable ingredients, such as excessive sugar, salt, or unhealthy fats.¹¹

QR codes and their relevance in food packaging

QR codes, short for quick response codes,¹² are two-dimensional barcodes that smartphones or QR code readers can scan to access digital information.¹³ They have gained significant relevance in various industries, including food packaging, due to their versatility and ability to provide quick and convenient access to additional content. QR codes are black squares arranged on a white background, typically square or rectangular.¹⁰ These codes can store significant data, including text, URLs, contact information, etc. When scanned using a smartphone or QR code reader app, the encoded information is decoded and presented to the user.¹⁴ QR codes provide an innovative and interactive way to enhance the information available on food packaging.¹⁵ Food packaging is often limited in space, making it challenging to include comprehensive nutritional information, recipes, or other relevant details.¹⁶

QR codes address this limitation by enabling access to a broader range of information through a simple scan, enriching the consumer’s experience.¹⁷ QR codes on food packaging can link to digital platforms offering nutritional information, ingredient lists, allergen warnings, and dietary guidelines. This allows consumers to make informed choices based on their dietary needs. QR codes also provide recipe suggestions, cooking instructions, and meal preparation tips, promoting a more engaging and enjoyable cooking experience.
